Let's talk about the installation steps of bridge sound barriers
1. Contact the bridge sound barrier manufacturer and negotiate with the manufacturer to formulate a suitable sound barrier installation plan, determining the materials, specifications, style, and color, etc.
2. Sign a purchase contract to customize the sound barrier.
3. Based on the design drawings provided by different manufacturers, prepare the basic data processing work in advance.
4. When unloading the bridge sound barrier, different strength and insufficient strength lifting belts should be used as loading and unloading slings. Hard slings such as steel wire ropes are prohibited to prevent scratches and tears of the sound-absorbing panels.
5. Install the thin nuts and spring washers under the bridge sound barrier column; adjust the position of the column, and the spacing should be vertical.
6. After installing the screen panel, adjust the bottom edge of the top cover so that it overlaps with the soft wire at the top of the column's cable installation cover, then drive in self-tapping screws to secure it. During the installation of the bridge sound barrier, it is necessary to check the straightness of the gaps in the screen panels with overall sound barrier function, adjust the baseline to a straight line, and the bridge sound barrier column blocks the installation of the screen. The bottom pad of the sound barrier should be high. If the bottom gap is large, it will cause bottom leakage, greatly reducing the sound insulation effect of the sound barrier. The current solution is to install a cover plate, which needs to be fixed with rivets.
Is the bridge sound barrier useful for high-rise users?
The installation of the bridge sound barrier will also benefit high-rise users. The sound is blocked by the sound barrier and then dissipates from above, which will greatly reduce noise. However, the specific noise reduction effect depends on the height of the sound barrier and the distance between the residents and the sound barrier. Sound holes or louvers will have a better sound barrier effect, and the top corner will also enhance the effect.
For bridge sound barriers, the noise reduction effect of high-rise residential buildings has been studied within a large height range. Monitoring of the sound pressure level on different floors of high-rise buildings before and after the construction of sound barriers shows that when the bridge sound barrier is located on the lower floors of high-rise buildings, the noise reduction effect is significant, and the floors with better noise reduction effect are the 6th floor.
Outside the sound shadow zone, the sound barrier can still reduce the noise of noise-sensitive buildings, and the noise reduction effect will decrease with the increase of building height. The distribution density of vehicles in different lanes has different effects on noise reduction.
Bridge sound barriers have a great impact on noise reduction. Currently, the methods currently used in transportation can be reduced by installing sound barriers, and the reduction in decibels is significant, reaching noise reduction standards.
It provides a quiet environment for people's life, work, and study. In addition, the sound insulation layer now considers not only noise reduction but also landscape effects. In order not to damage the surrounding environment, there are many choices for sound barriers, and the current transparent sound barriers are widely used and can blend with the surrounding environment, making them widely applicable.
Okay, that's all for today's introduction. Thank you for watching.
